Abstract [en]

This research explores the use of psychometric techniques to improveunderstanding of psychological mechanisms underlying judgment ofexcreta as fertilizer in agriculture including other excreta-relatedactivities. Participants consisted of environmental health students,smallholder farmers, and traders in rural and urban Rwanda andUganda. Thefinding reveals an inverse relationship between risk andbenefit judgments. This relationship holds for the three groups ofparticipants with significant risk and benefit correlations ofp<.0001.Thisfinding is consistent with other studies in showing that affectplays a key role in risk perception, judgment, and decision-making.Building on thisfinding, we conclude that individuals with high riskand low benefit judgment for excreta-related practices would eschewthem or emphasize strict standards. Individuals with a high benefit andlow risk judgment would engage in excreta management practicesregardless of the actual risks involved. Thisfinding is relevant for riskcommunication and risk management as it indicates that individualsdo not rely only on risk management information they receiveconcerning excreta and related risks but also depend, to an extent, ontheir feelings about these substances when making judgments anddecisions regarding the purpose for using excreta as fertilizer and thelevel of exposure they can tolerate and manage.
